DRAINAGE WAY

A drainage way, or ditch, is "a man-made open drainage way in or into which excess surface water or groundwater drained from land, storm water runoff, or floodwaters flow either continuously or intermittently drain" (Boone country 2017). Drainage ways are also known as watersheds. They can be small and modest, or large and ever-flowing through county to county. Some drainage ways or watersheds "encompass thousands of square miles and may contain streams, rivers, lakes, reservoirs, and underlying groundwater that are hundreds of miles inland" (2017). The water that flows though drainage ways may eventually end up in a larger body of water such as the Mississippi River, whether it started from there or ended there. Any land that has water that runs off ,such as parking lots, runs down into rivers and oceans via watersheds or drainage ways. An example of a drainage way or watershed is Hadley-McCharney Diversion Ditch in Missouri which drains into the Mississippi River.
